Let me illustrate with an example: Let's say you have solution of something we'll call AB and another of CD (just made up names), where both AB and CD are soluble. In one solution you'd have A+ and B- ions, and in the other you'd have C+ and D- ions. When you mix the two solutions, you'd have all four types of ions in the same solution. But let's say that compound AD is NOT soluble. Whenever an A+ ion encounters a D- ion in the solution, they will stick together and form this insoluble compound AD. Because it is insoluble, it will form a solid, and that solid is the precipitate you see.
If, using this same example, all of the possible combinations of ions, in other words AB, AD, CD, and CB are soluble compounds, then you will not form a precipitate when you mix them because when the ions meet, even if they come together momentarily, they will just as quickly redissolve.

What else can I help you with?
How can one determine if a precipitate will form from a given Ksp value?
To determine if a precipitate will form from a given Ksp value, compare the ion product (Q) to the Ksp value. If Q is greater than Ksp, a precipitate will form. If Q is less than Ksp, no precipitate will form.
For a precipitate to form do both products have to be soluble?
No, for a precipitate to form, at least one product must be insoluble in the solution. When two soluble reactants combine, they can form an insoluble product known as a precipitate, which will then separate out of the solution.
What chemical substance will form a precipitate with NH4Cl solution and also with K2CrO4?
A chemical substance that will form a precipitate with NH4Cl solution is AgNO3, resulting in the formation of a white precipitate of AgCl. With K2CrO4 solution, Pb(NO3)2 will form a yellow precipitate of PbCrO4.
What does water droplets precipitate as?
Water droplets can precipitate as rain, snow, sleet, or hail depending on the atmospheric conditions in which they form and fall.
How can one predict if a precipitate will form in a chemical reaction?
One can predict if a precipitate will form in a chemical reaction by looking at the solubility of the reactants. If the product of the reaction is insoluble in the solvent, a precipitate will likely form. This can be determined by consulting a solubility table or conducting a solubility test.
Will Nibr2 and AgNO3 form a precipitate?
Yes, Nibr2 and AgNO3 will form a precipitate when mixed. This reaction is a double displacement reaction where the insoluble silver bromide (AgBr) precipitate will form in solution.

Can you see a precipitate form?
yes. a precipitate is a solid formed when two liquid solutions combine.
Is H2O a precipitate?
No, H2O (water) is not a precipitate. Precipitates are solid substances that form from a chemical reaction in a solution. Water remains in liquid form.
What is form after the solution is in mixture?
Are you talking about precipitate
What does water droplets precipitate as?
Water droplets can precipitate as rain, snow, sleet, or hail depending on the atmospheric conditions in which they form and fall.
Does sodium chloride form a precipitate with soap solution?
Sodium chloride is needed to precipitate soap from solutions.
How can one predict if a precipitate will form in a chemical reaction?
One can predict if a precipitate will form in a chemical reaction by looking at the solubility of the reactants. If the product of the reaction is insoluble in the solvent, a precipitate will likely form. This can be determined by consulting a solubility table or conducting a solubility test.
Does mixing sodium hydroxide and calcium nitrate form a precipitate?
Mixing sodium hydroxide and calcium nitrate will not form a precipitate. Instead, it will form solutions of sodium nitrate and calcium hydroxide.
Will KNO3 and NaCl form a precipitate when mixed together?
No, KNO3 and NaCl will not form a precipitate when mixed together. Both compounds are soluble in water and will remain in solution.
